Problem in database fields creation using default class of B1DE Wizard

Question

Hi Experts
In an AddOn I am creating database fields in default class "Project_DB'. It does not give any message weather it creates fields or not. My code for database creation is given below
Namespace FormARE
    Public Class FormARE_Db
        Inherits B1Db
        Public Sub New()
            MyBase.New
            B1Connections.theAppl.StatusBar.SetText("Please wait. AddOn is updating database", BoMessageTime.bmt_Long, BoStatusBarMessageType.smt_None)
            Columns = New B1DbColumn() {New B1DbColumn("OCRD", "BondNo", "Bond No.", BoFieldTypes.db_Alpha, BoFldSubTypes.st_None, 20, New B1WizardBase.B1DbValidValue(-1) {}, -1), New B1DbColumn("OCRD", "BFrDate", "Bond From Date", BoFieldTypes.db_Date, BoFldSubTypes.st_None, 10, New B1WizardBase.B1DbValidValue(-1) {}, -1), New B1DbColumn("OCRD", "BTDate", "Bond To Date", BoFieldTypes.db_Date, BoFldSubTypes.st_None, 10, New B1WizardBase.B1DbValidValue(-1) {}, -1), New B1DbColumn("OINV", "Cntner_no", "Container No.", BoFieldTypes.db_Alpha, BoFldSubTypes.st_None, 20, New B1WizardBase.B1DbValidValue(-1) {}, -1), New B1DbColumn("OINV", "Cntnr_Seal", "Container Seal No.", BoFieldTypes.db_Alpha, BoFldSubTypes.st_None, 20, New B1WizardBase.B1DbValidValue(-1) {}, -1), New B1DbColumn("OINV", "Cust_Seal", "Custom Seal No.", BoFieldTypes.db_Alpha, BoFldSubTypes.st_None, 20, New B1WizardBase.B1DbValidValue(-1) {}, -1), New B1DbColumn("OINV", "ctryOrgn", "Country of Origin", BoFieldTypes.db_Alpha, BoFldSubTypes.st_None, 20, New B1WizardBase.B1DbValidValue(-1) {}, -1)}
            GC.Collect()
            B1Connections.theAppl.StatusBar.SetText("Successfully updated database", BoMessageTime.bmt_Short, BoStatusBarMessageType.smt_Success)
        End Sub
    End Class
End Namespace
It does not give first message. and second message come properly and immediately when I start the AddOn. I checked it makes all fields accuratly. But when I open the related form it gives error message "Data Source not found". I checked fields name are same as used in form and database .What can the reason? Should I use a simple function for creation of database fields which will run when a button is pressed? Is it fine to using default class for database fields creation?
Thanks
